Great job, Cornelis, thank you!
Now let's add the Dresden piece which, as well as one of your Spanish items, clearly shows signs of hard employment as a broken tooth has been repaired by copper soldering. It was made in Italy in about 1585 and given to Christian I, Elector of Saxony, in 1587.
Please note that all these multifunctional items are actually combination weapons. In the case of the Dresden combined blade catcher and breaker, you can see little riveted swivelling stops at the entrances beween the teeth: once the opponent's blade was caught between two teeth the stop would immediately prevent it from been withdrawn, and it could be broken.
I add more of these combined edged weapons from various museums; they are all united in a highly recommendable book:
Heinz-Werner Lewerken:
Kombinationswaffen des 15.-19. Jahrhunderts, Berlin, 1989, ISBN 3-327-00516-8.
Don't worry about the text being in German; the huge and detailed photos, as well as the datings and exact measurements, will be perfectly understood by everyone!
It comprises important items from the Met, The Royal Armouries Leeds, the German Historic Museum (DHM) Berlin and of course the Dresden museums.
Best,
Michael
